A toy includes a platform, a moving body, and a balance bar. The moving body has front and rear wheels rotatable about horizontal rotary axes, a turning wheel, and a drive unit coupled to the turning wheel and one of the rear wheels to drive movement of the moving body when the moving body is disposed on the platform. The turning wheel is rotatable about an axis perpendicular to the rotary axes of the front and rear wheels, and prevents the moving body from falling off the platform when the moving body moves to a peripheral edge of the platform. The balance bar has an intermediate fulcrum portion mounted pivotally on the moving body about a horizontal pivot axis, and two arm portions projecting from two opposite lateral sides of the moving body. Each of the arm portions has a distal section provided with a tray plate adapted for placing game tokens thereon such that a moment of force is applied on the balance bar to cause the balance bar to incline about the pivot axis with respect to the moving body according to the weights of the game tokens and the positions of the game tokens on the tray plates.
